I'm not a big fan of Big Al but cut the guy a break. He's a publicist not a scientist. The IPCC is supposed to be the gatekeeper on good science and they dropped the ball, not Gore. Gore and a lot of other well intentioned people have had to bear the brunt of another shoddy UN process.

Kevin is not the victim of sizism, he - and you and I - are victims of a common feature of modern life: perfect procedures, imperfect systems. Issues of how many seats can an airline cram into a cabin and America's eating habits aside, the Southwest policy sounds pretty reasonable. Oversize passengers buy a second seat and get a refund if the plane isn't full. So how does it happen that Kevin get's so far along the chain of events that it causes everyone involved a lot of unnecessary pain and embarrassment? The captain who threw Kevin off the plane was enforcing a procedure. Nobody was taking any responsibility for the system. What happened when Kev bought his ticket? Did a screen come up - before the plug in your credit card number screen - warning Kev that if you're over a certain weight you have to buy two seats? What happened when Kev arrived at the check in counter? Are the check in staff blind? How hard is it to notice that man or woman is 'of size' and won't fit into a seat my eleven year old daughter can barely squeeze into (she's big for her age)? Isn't there a role here for the security staff? It IS a safety issue. Plane skids off the runway a large passenger will have difficulty getting down that rabbit trail called an aisle. Kevin's embarrassment, and the discomfort of his seatmates, could have been avoided at any of several steps along the way. But it wasn't, because everyone is responsible for a procedure, but no one is responsible for the system.

Tinkering is hard wired into the human brain. Lockouts are just another level of challenge. I strongly recommend Neal Stephenson's essay/book In the Beginning Was the Command Line. He presents a very good argument for why the proprietary OS business is unlikely to remain profitable for much longer. Reading that book saved me from falling prey to the siren Apple. I was shopping for a new laptop and considering a switch to Apple. Why not? Everyone I know that has one just raves about it. So there I was, sitting in a glitzy Apple showroom, surrounded by shelves of really cool stuff, fingers caressing an elegantly designed wafer of plastic and silicon...and I recalled Stephenson's rap about Apple and MS selling a vision. It's Disneyland. You want to tinker, don't go to Disneyland.
